The standard measuring range for capacitive humidity sensors, is predominantly at 10-90% relative humidity (RH). The measuring range of high quality devices may be between 0% and 100% RH.

A major advantage of the capacitive measuring method, is the wide temperature range in which humidity measurements can be performed. For instance, some modern, industrially used humidity sensors allow for measuring humidity and temperature with a standardized output signal at -40°C to 180°C.
